Sir Tom Jones has been rushed to hospital with a mystery illness - forcing him to cancel tonight's live show in Chester.

A statement posted on his Twitter told fans he was sadly pulling out of the gig.

"It is with regret that we have to postpone Tom Jones' performance at Chester Racecourse this evening," it read.

"The show will be rescheduled for Sunday 12th August. All tickets still remain valid for the rescheduled date. If you are unable to attend the rescheduled date, refunds will be available at point of purchase."

The statement went on: "Sir Tom Jones has a bacterial infection for which he is being treated in hospital.

"The condition is being well managed and we are hoping for a speedy recovery. He is extremely sorry and disappointed not to be able to perform tonight and sincerely apologises for inconveniences caused to the audience and all those who are involved in the event."

The 78-year-old singer made the decision after falling ill and being advised to rest by doctors.

He's since apologised personally while tweeting from his hospital bed.

"I am so sorry for cancelling last night's show in Chichester, it's the worse feeling having to let down everyone who was coming as well as everyone who is involved with the event" he wrote.

"I know many of you travel considerable distances and make plans with friends and family that take a lot of effort, and it is so disappointing when things don't go right."

He added: "Although I can't perform again tonight at Chester Racecourse, the good news is that we can get another date in Chester on August 12, so hopefully I will see you there.

"Until then, a sincere thank you for your support and understanding."

Fans were told about last night's cancellation with a tweet posted to Tom's official account at 5pm on Wednesday.

The statement read: "It is with regret that we have to cancel Tom Jones' performance at Stansted Park this evening.

"Unfortunately, Sir Tom is unwell and has been advised by doctors not to perform. All ticket holders will receive a full refund by contacting their point of purchase. We apologise for any inconvenience this causes and we wish Tom well."

The Sex Bomb singer was due to perform tonight in Chester then scheduled to tour Germany and Finland before heading back to the UK in August.

It's not the first time Tom has been blighted by ill health on tour.

In September 2017 he cancelled his US tour just five days before it kicked off after undergoing a hip replacement operation.
